My next box idea

i was thinking of firing the sub forward in a upward slant and the port downfiring. as you know i took out my backseat and made a little platform to hold the box. there is about 6 inches of space between the platform and the floor of the car.

the reason i want to do this is so the bass from the port will resonate off the floor of the car therefore be louder.

i could also do subs up and the port downfire.

what do you think. will it work?

I'm sure one of the guys who builds tweaky SPL boxes can flesh this out, but I'm reasonably certain considering it's 3:30AM that that configuration would "extend" your port length.

Chad you have a hatch right? I normally saw best results when the port was firing up towards the back of the hatch..

well its kinda like a hatch. i think i might try that.

i got the idea of port downfiring from my home theater sub. i have a 12 inch klipsch sub and it has the port on the bottom and the sup firing forward.

do you think by having the port firing into the floor might change the port tuning also?

It won't change the port tuning but it will change the gain output from the box.. best explained I guess by saying if both boxes had the same tuning frequencies.. if you ran a sweep in both setups they might have a different "sweet note" although the box tuning is the same the gain seen from the cabin may or may not change..

If it don't work you can just double baffle the wrong to get rid of the old sub cutout and put the sub on top.. :-) .. no biggy hehe. Not everything works.. all depends on the car. Marshall helped me with a box design and I tried it and it did worse than my last setup. never know till it happens :-)
